Abstract
The invention discloses a polycrystalline phase carrier and a production method of the polycrystalline phase carrier. The polycrystalline phase carrier is formed by processing raw materials of quartz sand, household waste, coal gangue and kaolin. The polycrystalline phase carrier is characterized in that the polycrystalline phase carrier is composed of the following components by weight: 10-20 parts of the household waste, 10-20 parts of the coal gangue and 30-40 parts of the kaolin. The production method is characterized by the following steps: firstly, screening the household waste: screening the household waste from a municipal garbage landfill, removing waste and old metals, plastics and the like, and reserving the screened waste for later use; weighing 40-60 parts of the quartz sand,10-20 parts of the household waste, 10-20 parts of the coal gangue and 30-40 parts of the kaolin by weight, filling into a ball mill to grind and make mud; after mud making, processing and shaping a carrier gemule according to the general ceramic product technique, then drying and calcining at a high temperature, wherein the calcining temperature is at 1270-1580 DEG C; performing heat preservation for 9-10 hours; and discharging after cooling to obtain the polycrystalline phase carrier. The production method provided by the invention has the advantages of energy saving, environmental-friendliness, process cost reducing and easily accessible raw material. The polycrystalline phase carrier provided by the invention is mesh-hole-shaped in inner part of the carrier, high in porosity and good in permeability and can be widely used as a support filler in a plurality of catalyst carriers and petrochemical reactors.
Description
Technical field
The present invention relates in the industrial tower reactor assembly, make catalyst carrier, support a kind of polycrystalline phase carrier and a making method that filler is used.
Background technology
Be used at present the industrial tower reactor assembly and make catalyst carrier, the product that supports filler is numerous.If any plastic products, ceramic, metallic article etc.Their weak point is: plastic products are easily aging, and service life is short; And ceramic is poor, and raw material are difficult for obtaining, and processed complex and cost are high; Metallic article easy corrosion under acid-base condition gets rusty.
Summary of the invention
Not enough for above-mentioned the problems of the prior art, the present invention proposes a kind of difficult wearing out, cost is low, again the polycrystalline carrier preparation method of energy-conserving and environment-protective.
The scheme that technical problem is taked that the present invention wants to solve is: its raw material mainly are quartz sand, house refuse, gangue and kaolin.
Technical characterictic of the present invention is that it is configured with composition by weight: quartz sand 40-60 part, house refuse 10-20 part, gangue 10-20 part, kaolin 30-40 part.
The house refuse of indication of the present invention refers to the rubbish in the landfill yard of city, after screening, removes waste metal, plastics and other gravel in the rubbish, and wherein waste metal, plastics can be sold for waste and old purchasing station.
Making step of the present invention: at first screen house refuse, with its screening rubbish, remove waste metal at city life garbage landfill, plastics etc.Rubbish after sieving is for subsequent use.Then component takes by weighing by weight, quartz sand 40-60 part, house refuse 10-20 part, gangue 10-20 part, kaolin 30-40 part grinding in ball grinder mud processed of packing into, by general ceramic processes shaping carrier germule, its support shapes is fixed by customer requirement behind the mud processed, as: the series of products such as sphere, cylindricality, taper.Afterwards oven dry, high-temperature calcination gets final product.Calcining heat requires at 1270-1580 ℃.Be incubated 9-10 hour, come out of the stove after the cooling, can make polycrystalline phase carrier.
The invention has the advantages that: energy-conserving and environment-protective, cut down finished cost, raw material are easy to get, and its carrier inside reticulates the hole.Therefore porosity is high, transparent performance is good, can be widely used in as the support filler in multiple catalysts carrier and the petrochemical reactors to use.
The energy-conserving and environment-protective of indication of the present invention are: the one, and utilize house refuse to make raw material, turn waste into wealth, not only alleviate the pressure of domestic waste field, and reduced the pollution of environment; The 2nd, the burning of self in calcination process of the combustible in rubbish and the gangue provides required part heat in the calcining, thereby reduces short calcining cost of energy, reaches energy-conservation purpose.
The present invention at high temperature forms polycrystal phase skeleton body take quartz sand, kaolin as skeleton.Domestic waste makes to fill raw material, and high temperature after-combustion volatilization forms the carrier honeycomb hole, and gangue is as the consolidation raw material.Also have the part combustible in gangue and the house refuse, can be used as the usefulness of the energy in calcining, thus can the energy savings cost.
The alleged polycrystalline of the present invention refers to carrier mutually by high-temperature calcination, the crystalline phase body that the interior molecules structure generation is dissimilar, and the crystalline phase that produces among the present invention has α-SiO

Specific embodiment:
Example one: the screening house refuse, with its screening rubbish, remove waste metal at city life garbage landfill, plastics etc.Rubbish after sieving is for subsequent use.Then component takes by weighing by weight, 50 parts of quartz sands, 15 parts of house refuses, 15 parts of gangues, the 35 parts of grinding in ball grinder of packing into mud processed of kaolin are pressed general ceramic processes shaping carrier germule behind the mud processed, make the spherical post-drying, through 1400 ℃ of high-temperature calcinations.Be incubated 9 hours, come out of the stove after the cooling, can make polycrystalline phase carrier.
Example two: the screening house refuse, with its screening rubbish, remove waste metal at city life garbage landfill, plastics etc.Rubbish after sieving is for subsequent use.Then component takes by weighing by weight, 60 parts of quartz sands, 20 parts of house refuses, 20 parts of gangues, the 40 parts of grinding in ball grinder of packing into mud processed of kaolin are pressed general ceramic processes shaping carrier germule behind the mud processed, make the column post-drying, through 1560 ℃ of high-temperature calcinations.Be incubated 10 hours, come out of the stove after the cooling, can make polycrystalline phase carrier.
After testing, the physical and chemical indexes of this polycrystalline phase carrier sees the following form:
